3) Describe problem: Not really a problem, just an observation and maybe a small annoyance. This happens with FireFox 3.5.3 but not with IE v8:
Hovering over the link the little popup window comes up okay and goes away okay when I move the cursor away. However say I click through and go onto the link, then return to the original URL using back arrow. Now the little popup window sticks with the cursor and follows it everywhere! It goes away only when I hover over the original link and go off of it.
